I'll solve this step by step by analyzing the food web diagram and answering each question.
First, let's understand the food web structure:
Looking at the diagram, I can see:
- Grass is the producer (at the bottom)
- Grasshopper eats grass
- Mouse eats grass
- Rabbit eats grass
- Lizard eats grasshopper
- Snake eats mouse
- Hawk eats rabbit, lizard, snake, and mouse
Now I'll answer each question one by one.
## Question 11: In the food web diagram which TWO organisms are secondary consumers?
Secondary consumers are organisms that eat primary consumers (herbivores).
Let me trace the food chain:
- Primary consumers (eat producers): Grasshopper, Mouse, Rabbit (they all eat grass)
- Secondary consumers (eat primary consumers):
- Lizard eats grasshopper (primary consumer) → so Lizard is a secondary consumer
- Snake eats mouse (primary consumer) → so Snake is a secondary consumer
- Hawk eats rabbit, lizard, snake, mouse → Hawk is both secondary and tertiary consumer
Looking at the options:
A. Rabbit, Snake - Rabbit is a primary consumer, not secondary
B. Hawk, Grasshopper - Grasshopper is a primary consumer
C. Lizard, Snake - Both are secondary consumers (Lizard eats grasshopper, Snake eats mouse)
D. Hawk, Lizard - Hawk is also a tertiary consumer
The correct answer for Question 11 is C. Lizard, Snake.
## Question 12: In the food web above, the mouse and grasshopper are identified as:
Mouse and grasshopper both eat grass (the producer), making them primary consumers.
Looking at the options:
A. Primary Consumers - Correct
B. Secondary Consumers - No, they don't eat other consumers
C. Top Consumers - No, they are eaten by other animals
D. Producers - No, they don't produce their own food
The correct answer for Question 12 is A. Primary Consumers.
## Question 13: Identify a top consumer from the food web.
Top consumers are at the highest trophic level and are not preyed upon by other animals in this food web.
Looking at the diagram:
- Hawk eats rabbit, lizard, snake, and mouse
- No arrows point away from the hawk to another predator
- So the hawk is the top consumer
Looking at the options:
A. Hawk - Correct
B. Mouse - Eaten by hawk and snake
C. Snake - Eaten by hawk
D. Lizard - Eaten by hawk
The correct answer for Question 13 is A. Hawk.
Final Answers:
11. C. Lizard, Snake
12. A. Primary Consumers
13. A. Hawk
